▪Case Management:
Environmental lead exposure continues to cause harm, particularly to young children and pregnant women. This section of the PHPR offers guidance on the provision of lead screening and follow-up services for children 6 months – 6 years of age. Lead screening and follow-up guidelines for pregnant women are included in the Prenatal Section of the PHPR.
According to the Centers for Disease Control and Prevention (CDC), case management of children and pregnant women with elevated blood lead levels involves the coordination, provision and oversight of services required to reduce lead levels to below a level of concern. A hallmark of effective case management is ongoing communication with the caregivers and other service providers, and a cooperative approach to solving any problems that may arise during efforts to decrease a patient’s elevated blood lead level, and eliminate lead hazards in the patient’s environment.
Case management is much more than a simple referral to other service providers. There are 8 components, which should be under the purview of a registered nurse:
Client identification and outreach Individual assessment and diagnosis Service planning and resource identification The linking of clients to needed services Service implementation and coordination The monitoring of service delivery Advocacy Evaluation*
Case management should occur for every child with a 2nd blood lead level of 10ug/dL or greater and for every pregnant woman with a venous level of 5ug/dL or greater. Children and pregnant women with elevated blood lead levels become “health department patients” when their cases are brought to the attention of staff, even if they are or have been receiving direct clinical services elsewhere. They will remain a health department patient until patient case closure.
The report forms are used to coordinate communication between the LHD lead case managers and the state HHLPPP NCI in an effort to assure that all children with an EBLL receive appropriate and timely care. The KHHLPPP NCI monitors incoming lab data and compares this with identified EBLL children reports sent from the LHD. A HHLPPP Initial Report Form includes demographics including *zip code, contact information, social security and a Medicaid number if relevant, actions/interventions marked for appropriate BLL’s, dated, and initialed where appropriate, as soon as the health department case manager becomes aware of a child with a BLL of 10µg/dL or greater. *A zip code must be included to enter the data into the system.
The KHHLPPP initial report form must be filled out for all children with a 2nd blood lead level of 10 -14µg/dL or confirmed BLL of 15 µg/dL or greater and for every pregnant woman with a venous BLL of 5µg/dL or greater. The original report is to be placed in the patient’s chart and a copy of this form may be faxed or mailed to the KHHLPPP NCI.
After the completed Initial Report Form has been sent to KHHLPPP, updates can be entered on the HHLPPP Monthly Report Form. This form should be kept in in patient’s chart and updated as appropriate with follow-up
Page 5 of 18 Kentucky Public Health Practice Reference Section: Lead January 31, 2012 Kentucky Healthy Homes and Lead Poisoning Prevention Program (KHHLPPP)
BLL’s and necessary interventions noted. Copies of the monthly report form will need to be faxed to the KHHLPPP NCI when new entries are made.
If the patient’s BLL increases, thus changing needed interventions please send updated information with appropriate interventions noted to the KHHLPPP NCI.
▪VERBAL RISK ASSESSMENT FOR LEAD POISONING
Review each of these questions at every preventive service for all children ages 6 months–6 years. American Academy of Pediatric (AAP) recommends verbal lead risk assessment to be performed at ages 6, 9, 12, 18, and 24 months, and ages 3, 4, 5, and at 6 years with appropriate action to follow if blood lead level is positive. AAP recommends and Medicaid requires blood lead testing at ages 12 and 24 months. These questions are also included on the Health Risk Assessments (ACH 25, 90 and ACH 91).
Pregnant Women Review each of these questions at the positive pregnancy test visit or initial prenatal visit to determine if patient is at-risk.
A copy of the Verbal Lead Risk Assessment Questionnaire can be found in the Forms and Teaching Sheets/Teaching Sheets Section under Lead/ACH 25 section of the PHPR. The questionnaire reviews potential patient risks such as:
1. Does the patient live in or visit a building built before 1978 with peeling/chipping paint or undergone recent or ongoing remodeling (dust)? 2. Does the patient or any other members of the household (child’s playmate/ brother/sister/ patient’s spouse) have a history of elevated blood lead levels or who has had lead poisoning? 3. Does the patient or someone who visits or in the household work in an occupation known or suspected to involve lead? Common industries using lead include but are not limited to: Auto mechanics/bodywork Plumbing Farm/Migrant Farm Work Blowing Glass Jewelry Making/Repair Furniture Refinishing Gardening Metal Sculpting Renovation Work Painting Stained Glass Painting Roads Printing Car/Boat repair Metal Work/Welding Casting Aluminum Firing Ranges Plastics manufacturing Ceramic Making Firearms/Firing Range Radiator Repair Battery Recycling/Smelting/Recycling Making Bullets/Sinkers/lead toys High Construction Area Electronic soldering Home Repairs/Remodeling Bridge Repair/Painting Smelting Metals/ Scrap yards
4. Does the patient use any folk remedies that may contain lead or use pottery or ceramic ware for cooking, eating, or drinking or participate in hobbies that may involve lead such as ceramic pottery, jewelry making, gardening or stained glass? IMPORTED COSMETICS: ▪ Middle East, India, Pakistan, Africa ▪ Kohl, Surma, Al Koh: a powder used both as a cosmetic eye make-up and applied to skin infections and the navel of a newborn child. And can be ingested when on hands ▪ Kajal: eye cosmetic when used can be ingested if on hands. ▪ Sindoor: a powder applied to face or scalp during ceremonies, mistakenly used as food FOODS: ▪ Middle East: ▪ Lozeena: a bright orange powder used by Iraqis to color rice and meat▪ Mexico ▪ ▪ Chapulines (dried grasshoppers): can be chocolate coated; grasshoppers eat chilies that are contaminated with lead from soil and area silver mine fallout

Other: ▪Bala Goli: a round, flat, black bean dissolved in ‘gripe water’ and used for stomach ache. ▪Kandu: a red powder used to treat stomach ache.
5. Does the patient live near a busy road/ highway? Soil around the home could be contaminated by the leaded gasoline fallout, on the soil or in water (cisterns/wells) for many years following contamination and can get on a child’s hands. Lead can also be absorbed from the soil in fast growing plants such as Kale, spinach, and other garden vegetables from the soil and then consumed by animals and humans and can lead to increase in blood lead levels.
Document in the medical record when assessment was completed, any positive response(s) and action(s) taken:
If the verbal risk assessment is negative at each visit, a blood lead level test should be routinely done for all Medicaid children and children who reside in a **targeted zip code area at 12 and 24 months of age. A “Yes” or “don’t know” answer to any question on the risk assessment will warrant a blood test for lead poisoning at that time, regardless of the child’s payer source or zip code area. Any child with a positive risk factor should be tested at least annually, until 6 years of age, as long as any risk factor exists.
A “Yes” or “don’t know” answer to any question on the risk assessment questionnaire will warrant a blood test for lead poisoning or a referral to the PCP.
See also the Prenatal section of the PHPR for Lead Screening Guidelines and Follow Up. Document in the medical record at the initial prenatal visit and anytime that the assessment was done, any positive response(s), and action taken according to the class chart guidelines located in the Prenatal section of the PHPR.
▪ BLOOD LEAD TESTING
Children and pregnant women regardless of payer source must have a blood test if they have a “Yes” or “don’t know” answer to any question on the risk assessment. For Medicaid enrolled pregnant women, Medicaid will pay for a blood lead screening, all others will need to pay per sliding fee scale or private insurance.
Children who receive Medicaid benefits or reside in a **targeted zip code area must have a blood lead test at 12 and 24 months of age.
All children between 2 and 6 years of age who receive Medicaid benefits or reside in a targeted zip code area must be provided a blood lead test when they present to the health department if they have not previously received a documented blood lead test.

*See Blood Specimen Collection Guidelines in the Lead Section and also the Lab Section
COMPLETION OF LABORATORY SUBMISSION FORMS Please fill out lab requisition forms accurately and completely, including your agency as the provider.
A. SCREENING This should be checked for the: initial capillary sample; first venous sample venous samples should always be taken on pregnant women re-screenings of children with levels equal to or greater than 10ug/dL and any screening test being repeated due to clot, insufficient quantity, or any other reason the sample could not be analyzed. B. CONFIRMATORY This should be checked for: the second capillary sample when the first capillary sample was equal to or greater than 15 micrograms per deciliter (lead poisoning). venous samples submitted as confirmatory samples after a first capillary sample was equal to or greater than 15 micrograms per deciliter and confirmatory tests being repeated due to clot, insufficient quantity, or any other reason the sample could not be analyzed. C. MEDICAL FOLLOW-UP This should be checked for: follow-up tests of ALL children who have been previously confirmed to be lead poisoned and medical follow-up tests being repeated due to clot, insufficient quantity, or any other reason the sample could not be analyzed.
NOTE: Venipunctures are confirmed specimens and if the results are greater than or equal to 15 micrograms per deciliter (µg/dL), this is to be considered a confirmed case of lead poisoning. Follow the recommended actions for levels greater than or equal to 15ug/dL as indicated in the “Guidelines for Blood Lead Levels and Follow-Up.”
NOTE: See Administrative Reference for payment procedures.
▪ HOME VISITS AND ENVIRONMENTAL MANAGEMENT FOR PATIENTS WITH ELEVATED BLOOD LEAD LEVELS (EBLL)
According to KRS 211.905, an inspection of the property where an EBLL child routinely spends more than six (6) hours per week should be completed to determine the existence of lead-based hazards.
Priority should be given to the child’s primary place of residence. The environmental investigations may include the visual as well as the comprehensive lead risk assessment to determine the existence of lead based hazards.
Environmental Management through home visits is one component of an on-going process related to the elimination of lead poisoning as a public health problem. Home visits and visual investigations help to: Identify areas in the home that could potentially be a source for lead exposure;
Provide suggestions and educational materials to the family in an effort to make the home lead-safe;
Page 8 of 18 Kentucky Public Health Practice Reference Section: Lead January 31, 2012 Kentucky Healthy Homes and Lead Poisoning Prevention Program (KHHLPPP) Reduce the patient’s current BLL to less than 10µg/dL by reducing or eliminating the amount of lead exposure;
Assure that patient’s with an EBLL receive timely and appropriate care.
Collaboration of the environmentalist and the lead case manager assures appropriate and timely environmental home visits and investigations for patients who are identified with EBLL’s. Interventions during investigations include: Informing the patient/parent/guardian/care giver of child’s blood lead level; review level of understanding; monitoring of blood lead levels, Reviewing what lead poisoning is and common sources of lead, provide educational materials; Reviewing health education and preventive lead poisoning strategies, provide suggestions in an effort to make home lead safe and to reduce the amount of lead exposure; Reviewing lead poisoning prevention diet, Reviewing patient’s physical status, including behavior problems/changes, nutritional status and specific habits such as placing fingers in mouth or eating dirt or paint chips; Establishing who is providing patients primary and acute health care; Visualize the patient’s home environment and child play areas to identify potential sources of lead; is the home pre-1978 and have chipping, peeling paint or dust throughout home and discuss emergency measures to reduce the patient’s lead hazard exposure; Assure the well-being of the child by referring to appropriate agencies; services may include social services for emergency or temporary housing agencies.
Home visits by a nurse or allied health professional as defined in the Home Visiting Section of the PHPR, are to be conducted for all children referred into or already receiving services in a health department clinic with a second blood lead level remaining at 10–14µg/dL or a confirmed blood lead level of 15µg/dL micrograms per deciliter or above and for pregnant women with a BLL of 10ug/dL or greater.
Upon receipt of EBLL results, the lead case manager is responsible for collaboration and referrals to the environmentalist or risk assessor for appropriate environmental investigations. For children identified as having BLL’s of:
2nd BLL of 10µg/dL or greater, a home visit and visual investigation are to be completed at the children and pregnant women’s primary residence to identify potential sources of lead. Confirmed BLL of 15µg/dL or greater (lead poisoning), in addition to the home visit/visual investigation, a referral for a lead risk assessment must be completed to a a certified risk assessor.
If your health department or district does not employ a certified risk assessor, please contact the KHHLPPP• 502-564-2154•275 East Main Street •Frankfort • KY •40621 If a lead poisoned child is referred to the health department and no environmental risk assessment has been completed on their current home, referrals for a lead risk assessment may need to be completed for those patients living in at-risk conditions.
Investigation of the Primary Address: The initial home visit should be initiated by the LHD lead case manager or home visiting nurse following time frames listed below (See Table 1). The visual investigation is generally completed by the environmentalist however can also be completed at the time of a home visit by a trained home visiting RN. Investigations should be conducted within the appropriate timeframes according to CDC’s recommendations. (See Table 1) However, KHHLPPP recommends timeframe of two (2) weeks for BLL’s 10-14ug/dL to visualize potential sources of lead and to review preventive education with the parent/guardian/.care giver and to prevent further elevation of the BLL.
Page 9 of 18 Kentucky Public Health Practice Reference Section: Lead January 31, 2012 Kentucky Healthy Homes and Lead Poisoning Prevention Program (KHHLPPP)
Table 1: Home Visit and Visual Investigation Blood Lead Level Time Frame for Assessment 2nd BLL 10-14ug/dL 4 weeks of 2nd BLL in this range 15-19.9 µg/dL 2 weeks; refer for comprehensive lead risk assessment 20-44.9 µg/dL 1 weeks; refer for comprehensive lead risk assessment 45-69.9 µg/dL 48 hours; refer for comprehensive lead risk assessment >70 µg/dL 24 hours; refer for comprehensive lead risk assessment
At the time of the assessment, preventive education should be reviewed with the parents/guardians/care giver. Preventive education includes discussing the child’s potential source of lead-based hazards and how to prevent further exposure to those sources, increase child’s hand washing with soap and water, house cleaning techniques such as damp dusting, wet mopping, and daily vacuuming of the home. Temporary measures to reduce further exposure are not required within a specific timeframe, however it is recommended to keep the child away from the potential sources. If the child’s BLL should increase to lead poisoning (BLL >15ug/dL), it is required per KRS 211.905 to correct any identified lead hazards within sixty (60) days. Temporary measures may include but are not limited to:
Blocking child from potential hazardous area with a barrier, (i.e. door, child gate); Using furniture to block child’s access to the hazard (i.e. furniture in front of a chipping window sill); Use of duct or masking tape and plastic or cardboard to cover an area of chipping/peeling surface until permanent work can be conducted; Daily damp dust, wet mop and vacuum with a hepa vac especially in the child’s play area; Wipe child’s toys clean, keep toys in clean dry tote, and placing tote in clean play area and limiting the child’s play to this area; (especially if child is crawling and/or in hand-to-mouth exploration stage); Keep child’s hands washed with soap and water, (germ gel does not remove lead), wash hands before snacks and meals and before any nap or bedtime (especially if child is crawling and/or in hand-to-mouth exploration stage); Exploring the possibility to relocate child(ren) and pregnant women from the home while renovation/remediation work is in progress.
A thorough visual investigation of the child’s home identifies possible sources of lead. The investigation should visualize both the interior and exterior environment of the child with attention given to child accessible painted surfaces, dust and soil. Other potential sources of lead should be considered during the assessment i.e., water, family occupation, hobbies, etc.
If the BLL remains elevated or at a level of lead poisoning and is not decreasing in 8-12 weeks, an environmental investigation may need to be conducted at another property where the child routinely spends more than six (6) hours a week.
The home visit/visual investigation form should include any pertinent information from the child's parent/guardian/care giver that is not already supplied on the referral form. This should include the following: How long the child has lived at this address Supplemental address information Number and names of children that live or visit here Owners name, address and phone number Child’s play areas, sleep areas, habits Parents occupations, hobbies, other possible sources.
Page 10 of 18 Kentucky Public Health Practice Reference Section: Lead January 31, 2012 Kentucky Healthy Homes and Lead Poisoning Prevention Program (KHHLPPP)
Lead Risk Assessments For children identified with confirmed lead poisoning, a BLL >15µg/dL, a lead risk assessment is required according to KRS 211.905 (1). Comprehensive Lead Risk Assessments referrals are made by the LHD case manager and should be conducted by a certified risk assessor within the appropriate time frames per CDC’s recommendations. (See Table 2)
Table 2: Comprehensive Lead Risk Assessment Blood Lead Level Time Frame for Type of Assessment Assessment >70 µg/dL Within 24 hours Comprehensive Lead Risk Assessment 45-69.9µg/dL Within 48 hours Comprehensive Lead Risk Assessment 20-44.9 µg/dL Within 1 weeks Comprehensive Lead Risk Assessment 15-19.9 µg/dL Within 2 weeks Comprehensive Lead Risk Assessment Persistent BLL at10-14ug/dL Within 4 weeks Comprehensive Lead Risk Assessment
The lead risk assessment report can take up to 30-90 days to process and receive.
The case manager must collaborate with the environmentalist to assure timely and appropriate environmental follow up. When the LHD receives its copy of the lead risk assessment report, both the case manager and the environmentalist should review the report to coordinate appropriate preventive strategies and interventions.
Follow-Up Home Visits Follow-up home visits also assure measures for lead poisoning prevention are continuing. Follow-up home visits are also indicated when:
a. Child fails to return for blood lead monitoring b. blood lead levels remain elevated c. blood lead levels are increasing d. at any other time the case manager feels a home visit would be beneficial

▪Case closure Case closure is determined according to the initial blood lead level and can be closed as follows: •B LL 10-14.9 µg/dL – Case closure is when BLL is less than 10µg/dL, repeat BLL as indicated.
• BLL 15 µg/dL and greater– Case closure is when BLL is less than 10µg/dL for at least 6 months; environmental hazards have been addressed; and there are no new environmental hazards.
When a child is closed to follow-up, according to PHPR guidelines, the date and reason for case closure, and any actions/interventions or comments should be recorded on the case management report in area provided.
For prenatal lead exposure, case closure ends for the pregnant woman at delivery of the infant. If the BLL is >25µg/dL, follow-up will be with the patients PCP. The newborn will need to be tested at delivery. A cord blood sample is to be used for testing at the time of delivery. Protocols for case management will be initiated for newborns with BLL’s >10µg/dL.
A case may also be designated as administrative closure if all directives, as enumerated in the “Follow- up/Internal Tracking/Referral” section of the PHPR, have been completed. The case manager must follow all procedures for closure in a ‘lost to follow up’ case closure.nal (If a case has been closed and at a later date is reopened, send a new Initial Report Form with initial BLL and updated information. Please do not continue on old file and write reopened.)

Medtox website for Guideline for collecting and handling blood lead samples video: www.Medtox.com, go to Medical testing, go to Filter paper testing, go to view collection video.
Attention: Steps performed before, during, and after collection are of paramount importance.
Lead is everywhere in the environment. Therefore, great care must be taken to remove lead from the hands of the patient and collector prior to collection. It will also prevent contamination of your collection site and work environment. Prepare your worksite in a sterile fashion prior to washing patients and your own hands for the specimen blood draw.
It is recommended for screening children who are younger than one (1) year of age to use the heel of the infant as a puncture site. Guidelines for this procedure can be found at the National Committee on Clinical Laboratory Standards. NOTE: The finger stick collection technique is more prone to environmental contamination than the venous and will affect specimen results. Special precautions are needed to prevent contamination.
CDC recommends confirmation on all lead poisoned results with a venous specimen.
Contamination errors are common in trace metal analysis, so precautions must be taken to eliminate or reduce them. Lead can be picked up by accident from work surfaces, from printed materials or from the hands of the collector. It can also come from the hands and the clothes of the child you are screening. The key to effective lead screening is to collect specimens that have not been contaminated.
To reduce the odds of contaminating your sample: Take special care when preparing your test area and supplies, use sterile fashion.
As much as possible, use only supplies that have been certified as lead free.
Label the liquid soap bottle that will be used for lead testing, “Use for Lead Testing Only”.
Handle all equipment with powder-free gloves. Powdered gloves may contaminate your sample.
Keep all screening supplies—which include your lancet, gauze pads, band aids, tissues, alcohol pads, and micro- collection vials—in a clean plastic box with a snap lid for storage.
When using bulk-packaged micro-collection vials, carefully pour the vials into a re-sealable plastic bag and close to store. Individually packaged kits or a full box of micro-collection vials can be stored as they are. All micro-collection containers from open packages should be stored in a covered plastic container.
There are many types of micro-collection vials you can use to collect samples, but all must be prescreened or certified as lead-free.
Page 13 of 18 Kentucky Public Health Practice Reference Section: Lead January 31, 2012 Kentucky Healthy Homes and Lead Poisoning Prevention Program (KHHLPPP) For Capillary tubes, most vials contain 200 to 300 micrograms per deciliter of blood, EDTA or Heparin tubes are required.
For Capillary Scoop micro-collection vials, these should be used with extreme caution because they have a high potential for contributing to lead and tissue contamination.
Choose a lancet with the appropriate depth to collect the proper amount of blood for the micro-collection vial you are using. Also, use retractable lancets that cannot be used more than once to avoid sticking a child unnecessarily Practice universal precautions and wear protective equipment.
Specimen Collection Technique Preparing the Collection Area: Before you begin, fill out your laboratory request form completely and write the child's name on the vial label or front of filter paper collection Card by applying bar-coded sticker from requisition into box on card, or writing name and patient ID number on card. NOTE: Information must match the requisition and cards without label or identifying information will NOT be tested. Information required for lab reporting and should be placed on lab requisitions include: First Name, Last Name, Middle Initial, Date of Birth, Patient address, City, State, Zip code, Social Security #/ Medicaid/Passport #, Child/Prenatal/Adult, and collection date. Prepare your collection area with a clean, disposable pad in a sterile fashion as to keep area contamination free and always have the following on hand: o Two gauze pads o Liquid soap o Two alcohol pads o Bandages o A self sheathing lancet o Biohazard bag o A micro collection vial or filter paper o Accessible sharps container o Specimen identification label
It's important that the technician/ nurse responsible for obtaining the blood sample is familiar with the techniques for obtaining a high quality blood lead sample, see CDC video at http://www.cdc.gov/nceh/lead/training/blood_lead_samples.htm Capillary/Finger Stick Technique 1. The nurse should help the child thoroughly wash their hands (or foot) with soap and water, as the collector is also washing their hands, paying special attention to the fingertips and under the finger nails and on nail beds, (absolutely do not use gel type sanitizers). If the child will not let the nurse wash their hands, the parents should thoroughly wash their own hands and then the child’s hands, again paying attention to area of the nails.
2. Rinse hands thoroughly.
3. Since recycled and colored towels may have traces of lead, it's best to let hands air dry or use white, lead free towels.
4. To avoid contamination do not let the child's fingers touch any surface, you may need to hold the child’s hand in a gauze or paper towel until you get to your work area.

Although you can draw a sample from any finger, we suggest working with the ring finger. The ring finger is less calloused and somewhat less sensitive. Plus, it’s easy to palpitate above the puncture to produce and increase blood flow.
6. Massaging the child’s hand and the lower part of the finger before you make your puncture will calm the child and stimulate blood flow.
7. Clean the finger that you will puncture with an alcohol pad. If you see dirt on the pad, use a new alcohol pad until clean.
8. Allow finger to air dry or wipe dry with sterile gauze. NOTE: If alcohol remains on the finger, it will prevent the blood from forming a well-rounded drop and will contaminate the sample. Wiping will also prevent alcohol from getting into the cut and stinging. Remember to keep the finger isolated from the rest of the hand.
9. When you are ready for blood collection, hold the child's finger in a downward position.
10. Use the appropriate blade and lance the palm side of the finger. Do not lance the side or the tip.
a. Correct finger stick Puncture across grooves of fingerprint; a round drop of blood will form b. Incorrect finger stick: Puncture parallel to grooves of fingerprint; blood runs down finger; will not form into a drop. This enables the blood to form as a drop on the fingertip. If the puncture is parallel to the lines of the fingerprint, the blood will not form as a drop but will run down the finger making correct collection impossible.
11. Promptly blot the first drop of blood on a gauze pad and discard in the appropriate container. The first drop of blood is likely to contain excessive tissue fluid that can alter test results.
12. To collect a droplet of blood, keep the child's finger in a downward position and gently massage it to maintain blood flow. If blood flow is inadequate, gently massage the child's finger to stimulate more flow, but don't squeeze the finger because tissue fluid may dilute the sample. Avoid strong, repetitive pressure and do not scrape the finger during collection.
Capillary Tubes/Vial Collection
Hold the micro-collection tube at a 10 degree angle below the collection line. Touch the tapered end of the tube into the droplet of blood and not directly on the skin. Capillary action will cause the blood to fill the tube. As the blood starts entering the capillary tube, be careful not to allow air bubbles to enter. You will need to collect your sample within two minutes to avoid clotting.
Also avoid collecting smeared blood or blood that has run into the cuticle or nail area.
Depending on the micro-collection vial you use, the amount of blood you collect will vary. Fill tube to the appropriate line in order to have both the correct anticoagulant-to-blood ratio and to supply a sufficient amount of blood to the lab for testing.
Seal the micro-collection vial and gently invert the container 7 to 10 times to prevent clot formation. Clots can render the specimen unsuitable for testing. Page 15 of 18 Kentucky Public Health Practice Reference Section: Lead January 31, 2012 Kentucky Healthy Homes and Lead Poisoning Prevention Program (KHHLPPP) Carefully place the child’s identification label on the micro-collection vial vertically. If the label is not fixed vertically, the laboratory will not be able to read it. Filter Paper Collection Lead testing requires that a SINGLE large drop of blood FREELY falls and is absorbed uniformly by the filter paper. Do not scrape, smear, smudge, wipe or touch finger or blood to the filter paper, these specimens will be rejected.
Collect at least two large, separate blood drops that:
Evenly saturate the filter paper, i.e., the spot will appear the same on front and back of the paper (see examples, p. 2 on Medtox Guideline examples). Evaluate the sample collection. Examine the back side of the filter paper to ensure that the blood has soaked evenly through to the paper. If NOT acceptable, repeat finger stick and recollect sample on a new sample card. Are about the size of the black circles (½ inch diameter). NOTE: Blood spots do NOT have to be within the black circles but must be large enough for testing (2 spots with minimum 3/8 inch diameter). If drops are free falling, the drop will be large enough to read, do not touch blood or finger to paper. NEVER put a 2nd drop of blood on top of a spot of blood already on the paper (i.e., multiple drops), which makes the collection unacceptable for testing and will be cancelled as a smear, non-homogeneous, or unsuitable (see examples, p. 2 on Medtox examples). If a hemoglobin test is also requested, a 3rd acceptable free falling blood spot is required. A “HGB” circle is provided as a guide on the white Pediatric Lead/Hemoglobin blood sample card, however can be anywhere in the collection area as long as it does not overlap another blood drop. Dry collection Card: Allow the opened collection Card to air dry for at least 2 – 5 minutes. Place the dry card into a plastic bag and seal. NOTE: Samples received wet CANNOT be tested—occurs when cards are immediately placed into plastic bag or when filter paper is saturated with too much blood. Please let these cards dry. 13. Ship specimen promptly per protocol of the laboratory.
When the child's blood level results are received from the laboratory, consult PHPR Lead section for intervention guidelines according to blood lead results.
